Spikedfell drake

[awa]

i have a spiked fell drake pc that i will if every thing goes acording to plan be playing in a month or two. The thing im wondering is are their any prestige classes with synergy for natrual attacks the charecter has 6 racial hd and a level adjustment of 2 so prestige class that are relativly easy to get into would be preferable.

Soul Eater from Book of Vile Darkness is worth at least one level so you can deliver negative levels. It's full BAB and all good saves, so it's not bad to take to ten.
